Geranium 'Rozanne' has been voted one of the top 10 plants of the century and it's grown locally, which is an added bonus. Geraniums are versatile perennials that flower for several months through early summer and are at their best in July. One outstanding cultivar is Geranium 'Rozanne', easy to grow with gives masses of mauve flowers which emerge through the vigorous and lush foliage.
It looks at its best grown among shrubs and taller perennials where its lax habit can be used to full advantage.
'Rozanne' is a fast-growing herbaceous perennial. Among the geraniums, Rozanne is a taller, clump-forming hybrid.
Its leaves form mounds of slightly marbled, deep green foliage above which appear loose cymes of large (up to 5cm across) saucer-shaped, violet-blue flowers with pale whitish centres and red veins radiating out into the five petals. The flowering period is June to at least September.
Geranium ‘Rozanne’ is the registered cultivar name. It is thought to be a hybrid of Geranium himalayense and Geranium wallichianum ‘Buxton’s Variety’. On our nursery here at Griffins, we grow a few hundred of this variety each year.
Perfect for underplanting roses or filling a few gaps in the front of a border, coping well in full sun or partial shade. Most soils tolerated unless waterlogged. Water freely in the growing season. This plant is fast-growing and will benefit from a late summer chop to tidy up its habit and encourage production of fresh foliage and extended flowering. Cut back to one third of height with sharp shears or secateurs.
Geranium 'Rozanne' is great planted with other perennials such as Diascias, Osteospermums, Kaffir Lilies and Anthemis. Best planted in groups of 3, 5, 7 or more. Not much interferes with this Geranium, so it is generally trouble free as regards pests and disease!
